Study On The Prevention Treatment And Repairing Of Failure Of Cement Concrete Pavement

The cement concrete road noodles' conduct and actions is a kind of deluxe road noodles structure form, with the its strength Gao, stability and the durable good, bear heat and bear to wear and protect the expenses little etc. advantage but got an extensive application.According to current road noodles design theories, the road noodles each layer of structure function normal, layer the interface contact quality good cement concrete road noodles of the ideal, design and construction, generally want to pass by over a long period of time use and attain its design after use the time limit would open crack to break.But actual condition BE, a nice bit of road noodles at use 2-5 years even more short time after appeared the blemish of different degree or open crack.In the meantime, the cement concrete road noodles maintains cost Gao, health time be long, maintain the transportation interference of period severity, once break very difficult repair.As a result, recognize the clear water mire concrete road the creation disease of the noodles harm of reason and correspond of maintain a counterplan, is the problem that the engineering field needs to be resolve nowadays.The repair technique of the cement concrete road noodles emerges with the tide of the times after ising the damage which appears different degree along with the cement concrete road noodles.50's in 20 centuries and the beginning of 60's, some economic flourishing nations built parts of cement concrete road noodles while starting to be large-scale building high grade road of bear the heavy transportation in the world.These cement road the noodles expects after go to the 80's in 20 centuries, mostly near or exceed usage time limit and add of the development of traffic volume, cement road noodles bear of the stalk carry to continuously increase and cause most damages that the road noodles produces different degree.Therefore, the existing cement concrete road noodles protected to become the cement concrete road noodles a development an important contents within technique with repair.Speak from the technique, the quality problem of the concrete road of the influence cement noodles repair, the repair material that key adopt when lie in and repair craft.This text research around maintain of the cement concrete road noodles problem, to the cement concrete road noodles evaluation, the cement concrete road noodles of the familiar disease harm output reason and prevention and cure technique, the cement concrete road noodles of protect and maintain the bottom of the road front-panel of technique and cement concrete take off empty block up to settle a technique, road noodles gravamen whole causable car plank interaction to break to the cement concrete road noodles of the influence carried on a research.
